 In this paper, the wind speed data from meteorological observatory Bratislavomolinsk, Dolina were statistically analyzed. The data were analyzed based on Vable and Rayleigh distribution. The distribution parameters were estimated using maximum likelihood method. The both distributions were compared for their performance using the coefficient of determination and the root mean square error. The results indicate that the better performance can be obtained by the Vable distribution. This article was authored by Ivana Pabosikova, Zuzana Sedlyakova, and Jan Simon.
